Geometry: A Guided Inquiry
by G. D. Chakerian, Calvin D. Crabill, Sherman K. Stein · G.D. Chakerian, Calvin D. Crabill
A high school geometry textbook built around guided problems that ask students to discover results themselves. Develops congruence, similarity, area, polygons, circles, and proof through cooperative inquiry, helping readers reason about triangles and polygons rather than memorize theorems.
